Description of the Invention: The present invention relates to an apparatus for moving in and out of an optical disc drive, and more particularly to an advance and retract device for driving a movement of a suction-type optical disc drive to an advance/retraction sheet, and providing a vibration damping of the movement. [Prior Art]
由於光碟片儲存容量迅速增加，需要更快的光碟機存取速 度，以減少資料存取的時間》—般光碟機提升光碟機存取速度的 方式’主要為提高光碟片的轉速，而越高轉速所產生的振動越大， 影響光碟機正常讀寫，甚至造成讀寫失敗。 為了減少振動的影響，如圖1所示，本國第093114433號專 利申請案之先前技術，為一吸入式光碟機1，利用一進退片裝置2 前後滑動，以其上的滑槽3，帶動一連結於機芯4的滑柱5 ,在機 芯4受限制柱6拘束下，隨高低起伏的滑槽3移動，使機芯4產 生升降，讓設於機芯4上的主軸馬達7，箝住或退出光碟片D。當 主軸馬達7箝住且高速轉動光碟片D，以進行讀寫資料時，高速轉 動光碟片D所產生的振動’將經由主軸馬達7、機芯4傳至滑柱5, ^為滑槽3與滑柱5均摘性，輯柱5與賴3間亦設計Due to the rapid increase in the storage capacity of optical discs, faster access speeds of optical disc drives are required to reduce the time for data access. The way in which optical disc drives increase the access speed of optical disc drives is mainly to increase the rotational speed of optical discs. The greater the vibration generated by the rotation speed, the normal reading and writing of the optical disk drive, and even the failure of reading and writing. In order to reduce the influence of the vibration, as shown in FIG. 1 , the prior art of the Japanese Patent Application No. 093114433 is a suction type optical disc drive 1 which is slid back and forth by a feeding and unloading device 2 to drive a chute 3 thereon. The spool 5 connected to the movement 4 is restrained by the restricting column 6 of the movement 4, and moves with the undulating chute 3, so that the movement 4 is lifted and lowered, and the spindle motor 7 provided on the movement 4 is clamped. Live or exit the disc D. When the spindle motor 7 is clamped and the optical disk D is rotated at a high speed to read and write data, the vibration generated by the high-speed rotation of the optical disk D will be transmitted to the spool 5 via the spindle motor 7 and the movement 4, ^ is the chute 3 It is similar to the sliding column 5, and the column 5 and Lai 3 are also designed.

In order to achieve the purpose of the aforementioned invention, the impact of the camping on the disc is long and thin, and the gap is not effective. The elasticity of the disc is 8 386386. [Inventive content]: machine ί = = machine; The optical disc drive of the present invention advances and retracts 3 body and drive end, and the drive end is provided with a sliding rack, and the side slide of the main body? The i-slot has a high and low end, the low end is the retracting piece 4, and the high end is the feeding piece, and the elastic body is directly formed on the disc machine feeding and unloading device, is disposed at the periphery of the feeding end, and is located at the end of the chute end. In the position, one end of the elastic button body is connected to the body, and the other end is suspended from the protruding slot of the sliding slot. When the film is fed, the elastic sliding body is clamped to the sliding slot to restrain the vibration. [Embodiment] The present invention has been made in view of the above-described objects, the technical means employed, and the effects thereof, as described below with reference to the drawings. Referring to FIG. 2, the disc drive device 1 of the present invention drives a movement 11 up and down. The plate-shaped movement core includes a body 12, a main body, a motor 13, a reading head 14, and a protective cover 15. The frame body 12 is covered with a protective cover 15, and the protective cover 15 is provided with a hole groove 16. One end of the hole groove 16 protrudes from the spindle motor 13' and the reading head 14 slides in the remaining hole groove 16. On the side of the frame body 12 close to the spindle motor 13, a sliding column π is vertically protruded outward. The disc drive advance/unload device 10 is disposed on the side of the movement 11 near the spool 17. Referring to FIG. 3, the disc drive device 10 is in the shape of a rod and includes a body 18 and a driving end 19. The main body 18 is located at one end of the advancing and retracting device 10, and a plurality of sliding slots 2 are arranged on the upper surface thereof, and a sliding slot 21 is dug at the side. The sliding slot 21 has a high and low end, the low end is a retracting end 22, and the high end is a high end. The blade ends 23, 6 are provided with a latch body 24 at the periphery of the blade end 23. The latch body 24 is end-to-end coupled to the body 18, and the other end is suspended, slightly projecting the chute 21, and forming the edge of the chute 21 of the slider 23, and covering the position of the end of the chute 21. The driving device is disposed at the other end of the advancing and retracting device 10, and is provided with a sliding rack 25, which is driven by a fork disc drive mechanism (not shown) to move the advancing and retracting device 1 after delivery.刖 As shown in Fig. 4, the position at which the movement 11 is combined with the advance and retract device 10 is partially enlarged. Wherein, the slide column 17 protruding from the side of the movement body 11 of the movement 11 is inserted into the sliding groove 21 on the side of the ejection device 10, and the elastic body 24 is located at the sliding edge to form the edge of the sliding groove 21, so as to be stuck Slider 17 in the chute 21 = 9 = As shown in Fig. 5, when the optical disc drive is fed into the sheet, the advance and retract device 1 is slid as indicated by the arrow, and the spool 17 at the unloading end 22 of the chute 21 (such as the dotted line) As shown, as the chute 21 slides toward the sheet end 23, forcing the spool 17 with the motive core from the lower strip end 22, raised to the higher sheet end 23, when the spool 17 enters, the end of the end 23 The latch body 24 of the chute 21 is protruded against the top, and the end of the latch body 24 is forced to rise, so that the spool 17 enters the latch body 24 = and is caught by the latch body 24, and the movement is positioned. , start to turn the light = film, read and write data. Conversely, when the optical disk drive is unloaded, the advance and reverse film loading 10 moves in the opposite direction, forcing the spool 17 to leave the latch body 24, and the higher film end 23 returns to the lower unloading end 22 for unwinding. Therefore, in the disc feeding and unwinding device 10 of the present invention, when the sheet is fed, the elastic portion 24 is connected to the elastic of the advancing and retracting device 1 by the end, and the spool 17 female chute 21' can not only eliminate the spool 17 and the chute. 21 gaps, ^ Tian, = transmitted vibration to improve the reliability of CD-ROM reading and writing, at the same time, i. Secret; the body's elastic tight-sliding column, and non-soft material' can reduce the friction of the μ * clearance, effectively preventing the vibration of the optical disc drive. In addition, the present invention is formed on the disc drive advance and retract device, and is formed by the disc drive, and the optical disc machine is formed in a 1 a shape to simplify the components and reduce the cost. The above description is only for the purpose of illustrating the preferred embodiments of the present invention, and the scope of the present invention is not limited to the preferred embodiments, and any changes made in accordance with the present invention may be made without departing from the spirit of the present invention.
